![]() ![]() ![]() SAS Sort/Merge 4 proc sort dataleft 5 by id 6 run NOTE: There were 8 observations. SAS Merging combines observations from two or more SAS datasets based on the values of specified common variables (SAS merges more than 2 Datasets). In the example above, data set three is created by merging data sets one and two. A SAS-Oriented Introduction to Python Randy Betancourt, Sarah Chen. The SAS codes below show how they can be sorted and merged: MERGING : Merging is nothing but combining two or more SAS datasets horizontally In one to one merging dataset are not required to be sorted But for match. Suppose you create two data sets ( one and If you merge data sets without sorting, called one-to-one merging, the data of the merged file will overwrite the primary data set without considering whether or not two observations are the same. offers you a method by which you may join two or more datasets and output a combined product. To merge two or more data sets in SAS, you must first sort both data sets by a shared variable upon which the merging will be based, and then use the MERGE statement in yourÄATA statement. Step 1 : Both the data sets must be SORTED by the variable you want to use for merging Step 2 : The variable you want to use for merging must have same name in both the datasets Let's merge dataset A and B First, Sort both the datasets with PROC SORT. Understanding the MERGE Statement You merge data sets using the MERGE statement in a DATA step. ![]()
